For the outlined sphere model of a water molecule consisting of two small spheres with the mass m= 3 g and one large sphere with the mass M=16m, the moments of inertia are to be calculated in relation to the mutually perpendicular axes of rotation x, y and z. The z axis is perpendicular to the plane of the drawing and, like the x axis and the y axis, should run through the center of mass of the sphere model. The connections drawn in blue should have no mass, and the spheres should be assumed to have point masses

P.3) A thoughtful king once decided to update the drawbridge of his castle by attaching the middle of the drawbridge to the castle wall via a single linear spring with an unstretched length of 6 m. The drawbridge is 12 m long, has a rotational inertia of about O of 21,600 kg-m², and has a mass of 450 kg. The king has decreed that the spring constant shall be 690 N/m. What's the velocity with which the end of the drawbridge will strike the ground if it's released from a nearly vertical position? 不 6 m -6 m→ ww k 6 m
